Various exemplary embodiments relate to a pop-up electrical outlethaving, for example, a cylindrical profile. The pop-up outlet can berecessed in a surface, for example a countertop, and raised and loweredas needed. The outlet can be raised and lowered manually, using abiasing mechanism, through a motor and gear assembly, or through anothersuitable mechanism.

FIGS. 1 and 2 show an exemplary embodiment of a pop-up outlet 10, havingan upper portion including an outlet housing 12, a middle portionincluding a terminal housing 14, and a lower portion including a wiringhousing 16. The outlet housing 12 includes a cavity or chamber forreceiving at least a portion of an outlet, the terminal housing 14includes a cavity or chamber for receiving at least a portion of aterminal device and conductors extending from the terminal device to theoutlet, and the wiring housing 16 includes a cavity or chamber forreceiving at least a portion of wiring extending from an external sourceinto the pop-outlet.

A raise/lower mechanism 18 extends through the terminal chamber to raiseand lower the outlet housing 12 with respect to the terminal housing 14.The raise/lower mechanism 18 includes a translating 20 member that movesbetween an extended position (as shown) and a retracted position (notshown). The raise/lower mechanism 18 can be completely manual, include abiasing member, or include automated components such as a motor,threads, gears, telescopic members or other components as would beunderstood by one of ordinary skill in the art.

In various exemplary embodiments, the outlet and a platform 24 arepositioned in the outlet housing 12 and a cover 26 is releasablyconnected to the outlet housing 12, for example through a snap-fitconnection. As shown in FIGS. 4-6, the outlet housing 12 includes afirst snap-fit connection member and the cover 26 includes a secondsnap-fit connection member configured to mate with the first snap fitconnection member. In an exemplary embodiment, the outlet housing 12includes first and second openings having a resilient tab 28. The cover26 includes first and second protrusions 30 that snap-fit into theopenings. The protrusions 30 can be cantilever beam having a catch orhook member. The cover 26 can also include one or more posts 32extending into the outlet housing 12.

The outlet includes an outlet body 34 that is connected to the platform24, for example through a snap-fit connection. The platform 24 caninclude one or more openings with a resilient tab that respectivelyreceives one or more flexible prongs from the outlet body. The outletincludes openings for receiving a plug or other type of connector. Athree-prong opening having, hot, neutral, and ground receptacles areshown, although the outlet can include a two-prong outlet, a USB outlet,or any other type of electrical connector outlet as would be understoodby one of ordinary skill in the art. The outlet will include variousother internal components as would be understood by one of ordinaryskill in the art.

According to various exemplary embodiments, a gasket or seal 36 ispositioned around the outlet body 34 to resist or prevent liquids fromentering the outlet body 34 and negatively impacting the electricalcomponents of the outlet. FIGS. 7 and 8 show and exemplary embodiment ofthe seal 36. The seal 36 covers the front, back, sides and top of theoutlet body 34. The seal 36 can include openings or slits (not shown)positioned and sized to align and match the connector openings of theoutlet. The slits can be resiliently biased to a closed position, butcapable of moving to receive a connector, for example the prongs of aplug.

The terminal chamber includes an upper portion for receiving the outlethousing 12 in the retracted position. An upper plate 38 is connected tothe terminal housing 14 and an upper flange 40 is releasably connectedto the upper plate 38. As shown in FIGS. 4-6, the upper plate 38includes a first snap-fit connection member and the flange 40 includes asecond snap-fit connection member configured to mate with the first snapfit connection member. In an exemplary embodiment, the flange 40includes a set of four protrusions 42 that snap-fit into the openings.The protrusions 42 can be cantilever beam having a catch or hook member.The flange 40 can also include one or more posts 44.

An outer surface of the terminal housing includes an outer thread 46. Aring 48 having an inner thread is threadably connected to the outerthread 46. The pop-up outlet 10 can be positioned in a support, such asa countertop, with the flange 40 engaging a top surface. The ring 48 isadjusted and tightened to engage the bottom surface. Adjusting the ring48 allows the device to be installed in supports having differentdepths. The ring 48 includes a gasket to create a seal between the ringand the bottom surface of the support.

A terminal block 50 is positioned in the pop-up outlet 10 with a topportion in communication with the terminal chamber and a bottom portionin communication with the wiring chamber. One or more conductors 52extend from the terminal block 50 to the outlet body 34 to electricallyconnect the outlet with a power supply.

As best shown in FIGS. 9 and 10, the top portion of the terminal block50 includes a set of openings 54, for example a hot opening, a neutralopenings, and a ground opening. The openings are positioned near strainrelief members 56. Conductors 52 can extend through the openings 54 andbe received in the strain relief members 56. The strain relief members56 reduce or eliminate strain on the conductors as the outlet is raisedand lowered, helping to prevent disconnection of the conductors.

In an exemplary embodiment, the strain relief members include a base 56and a releasable clip 58. The base 56 includes a channel for receivingthe conductors a set of side projections or barbs. The clips 58 includea pair of side openings that receive the barbs in a snap-fit connection.

As best shown in FIG. 11, the lower portion of the terminal block 50includes a set of wiring terminals, for example a hot, neutral, andground wiring terminal. The wiring terminals can include an opening 60positioned orthogonal to a fastener 62, such as a screw, and a moveableplate for clamping an exposed end of a conductor that is inserted intothe opening 60. Different types of connections, including crimps andother fasteners can also be used.

As best shown in FIG. 2, the wiring housing includes different passagesfor receiving different types of power supply conductors or conduits.For example, a knock-out 64 is provided to receive a metallic cable orconduit. A strain relief member 66 having a pair of fasteners and amoveable strain relief plate can be provided for non-metallic cables.
